TLDR
A nonlinear eighth-order agonist-antagonist muscle model is identified, based on engineering analysis and design criteria, as the desired structure for the broad-range study of a variety of fundamental human joint movements as mentioned in this paper.Abstract:
A nonlinear eighth-order agonist-antagonist muscle model is identified, based on engineering analysis and design criteria, as the desired structure for the broad-range study of a variety of fundamental human joint movements. To complement this structure, systematic protocols, that combine material and geometrical information for each muscle, are developed to obtain the model parameter values needed for the various muscle constitutive equations. The parameters describing the four basic nonlinear relations are easy to visualize, representing the peak curve values and "shape" parameters. Elbow, knee, wrist, and ankle fiexion-extension and eye, wrist, and head rotation are simulated by this same model structure.read more

Eduardo Lázaro Martins Naves,Alcimar Barbosa Soares,Adriano Alves Pereira,Adriano O. Andrade +3 more
TL;DR: It is possible to conclude that the modeled reflex responses play a fundamental role in the upright posture, and the model may be used to formulate hypotheses about the origins of the somatosensory feedback deficits in postural control.

Décision motrice et contrôle modulaire d'un système hyper-redondant
TL;DR: In this paper, the authors propose a solution for the controle du mouvement peut etre guidee par les contraintes exterieures objectives (e.g. the position of l’objet a attraper), les couts/benefices explicite potentiels (i.e. a recompense monetaire), and les cout/benefice internes associes a chaque mouvment (e) depense d'energie).

The heat of shortening and the dynamic constants of muscle
TL;DR: In this article, a more accurate and rapid technique for muscle heat measurement was proposed, and some astonishingly simple and accurate relations have been found, which determine the effect of load on speed of shortening, allow the form of the isometric contraction to be predicted, and are the basis of the so-called "visco-elasticity" of skeletal muscle.

Data on the distribution of fibre types in thirty-six human muscles: An autopsy study
TL;DR: In this paper, the mean fibre type proportions of each muscle were examined and the spatial distribution of the fibre types was examined in order to determine whether this was random or not, and the number of closed fibers observed in the actual samples was compared statistically with the number expected to occur in a hexagonal lattice model, assuming a random distribution.

TL;DR: The author examines the relationship between ATPase activity of myosin and intrinsic speed of shortening, and the effects of nerve cross-union on properties of myOSin.

A physiologically based criterion of muscle force prediction in locomotion
TL;DR: The inversely-nonlinear relationship of muscle contraction force and the possible contraction duration is utilized in a method to mathematically predict individual muscle forces and shows substantial agreement with that activity pattern predicted when endurance is used as the optimization criterion.

Elasticity of soft tissues in simple elongation
TL;DR: A theoretical framework is presented in which the elastic properties of soft tissues can be described and it is shown that the mathematical formulation works well also in reducing published data on the series element of the heart and striated muscles, and the skin.
